lag spikes

Hi there, I don't know anything about PCs, I've tried doing some fixes threads have shared, some YouTube videos - etc, I just don't really know what the problem is to fix. My PC was working fine, could run games on high/ultra graphics with no problem, but recently I've been getting heavy lag...

Hi, i have had this problem for a while now but have fixed it by just running my games in 32 bit, but with new games coming out and 32 bit getting old a lot of new games don't support 32 bit My problem is whenever i run a 64 bit game, no matter what it is every minute or so i get a 15 second...
